RUN-2

RUN-2 reagent for temporary isolation and saving well-killing possesses high-effective plugging properties, limiting water inflow from washed-out pays without any reservoir productivity decrease. RUN-2 chemical reagent does not have any chlorine organic compounds that do not complicate the processes of oil transportation and processing. It is compatible with all types of formation water and does not provoke equipment corrosion.

SUCCESSFUL APPLICATION

THE FIELD EXPERIENCE IN APPLYING RUN-2 REAGENT PROVES THE REDUCTION IN WATER CONTENT AND THE GROWTH IN OIL PRODUCTION RATE. WATER-CUT PER WELL HAS REDUCED FROM 96 TO 50 PERCENT AND OIL PRODUCTION RATE HAS INCREASED FROM 0.2 TO 5.5 T/D

CHEMICAL COMPOSITION

• A synergistic mixture of oil solvents, alcohols and surfactants

LAB AND FIELD TESTS HAVE PROVED THAT PERMEABILITY RESTORATION FACTOR IN RESERVOIR BOTTOM-HOLE CONTACTING RUN-2 REAGENT HAVE COME TO 0.80 – 0.90.

ADVANTAGES OF USAGE

• Maximum preservation and restoration of reservoir native productivity
• After the completion of water shut-off (WSO) operation the reagent is self-destructing with hydro-phobic effect, and this enables to preserve or even to restore well productivity
• Controlled density in a range from 0.85 to 1.47 g/cm³
• Controlled “life time” of the composition in reservoir conditions (selected individually) is between 48 and 72 hours.
• Thermal stability is up to +130°С
• Zero corrosion and inhibition
• Does not require any additional pre-treatment of well bore-hole

APPLICATION OF RUN-2 SURFACTANT

• Technology of gentle well killing using RUN-2 hydrocarbon killing liquid
• Complex technology of targeted water shutoff with gel-polymer compositions with preliminary shutting off of oil zones with RUN-2 liquid hydrophobic composition
• Complex bottom-hole treatment technology using surfactant-acid compositions with hydrophobic shielding with temporary blocking RUN-2 composition
